My initial thought regarding the Web interface was not that we could or should replicate the GUI loci in a Web browser. My thought was that Loci can provide an HTML interface to _some_ of the _analysis_ loci, considering they are command-line, short-lived, output ASCI text, which will be formatted into XML anyway. Konrad and I have communicated quite a bit about the limitations of HTML. In fact, when I first mentioned XML, Konrad thought I was speaking of putting everything into a Web browser. Neither he nor I like the static interface of HTML browsers, so I will make a point that GUI loci will not look or act like one but will be very dynamic. In short, I think the Web interface can be a quick-and-dirty way for people without the Loci package to access the wealth of analysis loci we may someday amass. I appreciate that you looked into this. But I think this plan would be an enormous task, and probably best left to some heavy duty Java...which we don't want to use for reasons I've expressed before. Do you want to take on this Web interface project, as the simpler project I envisioned? I think the biggest part of this would be some sort of XML to HTML conversion, which is actually what XSL is all about. The problem with XSL is that browsers don't support it right now, and I don't think there is a specification for CML or BSML. And I think another big thing (providing no XSL is used) would be converting diagrams specified by XML into GIF format. You would have to write a program that would generate custom GIF's. Check out NCBI's "graphical view" of nucleotide data: http://www.ncbi.nlm.nih.gov/cgi-bin/Entrez/framik?gi=3647232&db=Nucleotide Also, the Web interface implementation will work from one server that I will have set up. It will act as a limited version of Loci, and will contact certain analysis loci around the Internet. This is no small project either. It will almost parallel Loci itself and use many of the same components. So, we must limit the types of views and analysis tools that the Web interface can handle.
